Discovery Passage Hydrophone Deployed 2020-07-15

The Ocean Sonics icListen AF Hydrophone 2523 was deployed on 2020-07-15 at Discovery Passage. Discovery Passage is a channel that is part of Inside Passage. It is located between Vancouver Island and the Discovery Islands and north of the Georgia Strait. This device is a Hydrophone. Hydrophones are devices containing transducers that convert underwater sound waves into electrical signals. They are acoustic instruments that can process data while they are being collected to produce calibrated waveform data. Hydrophones are typically used to study vocalizations of marine mammals, ship traffic and ambient noise. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

海洋声学公司（Ocean Sonics）的icListen AF型水听器（Hydrophone）2523于2020年7月15日部署于发现水道（Discovery Passage）。发现水道是内海航道（Inside Passage）的组成部分，地处温哥华岛与发现群岛之间、乔治亚海峡以北。该装置为水听器，水听器是一类搭载换能器（transducer）的设备，可将水下声波转换为电信号，属于声学仪器，能够在数据采集过程中同步处理，以生成经过校准的波形数据。水听器通常用于研究海洋哺乳动物的发声行为、船舶交通活动以及环境背景噪声。本次部署将设备固定于固定式平台之上。本次采集得到的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外公开，相关数据遵循既定规范开展质量保障工作并生成衍生数据产品。
